The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times.

What is the experimental probability of rolling a 1 or a 5?

Express your answer in simplest form.

Outcome 1 2 3 4 5 6
Number of times outcome occurred 10 6 4 8 6 6

Answer :

If they want a ratio it is 1/6 or 5/6
AL2006
Experimental probability  = 

         (number of times the result you wanted came up)
divided by
         (number of times you tried it) .

-- Number of times a 1 or a 5 came up  =  (10 + 6)  =  16

-- Number of times you tried it  =  (10 + 6 + 4 + 8 + 6 + 6)  =  40

-- Experimental probability  =  ( 16/40 )  =  2/5  =  40% .
